Flowgrids
The FGG FLOWGRIDS are most popular. They are used to measure the velocity pressure accross the complete duct area to provide an average velocity pressure measurement. They are manufactured as a standard galvanised duct frame with multiple Aluminium Flowprobes positioned internally. The total velocity pressure is captured by the FGG Flowgrids averaging tank to ptovide a smooth velocity pressure..
The all stainless steel VSS VELOGRIDS are used to measure the velocity pressure accross the complete duct to provide an average velocity pressure measurement. They are manufactured as a standard stainless steel duct frame with multiple stainless steel Veloprobes positioned internally. The total velocity pressure is captured by the VGS Velogrids averaging tank to ptovide a smooth velocity pressure..
The OAF Attenuator Flowprobe incorporates the CMR Alumimium Flow Probe and has a bottom and top bracket with expansion springs, so that the probe can be pushed into the attenuator slot and is held in position by the spring power and self tapping screws. The OAF Flowprobes are used to measure the velocity pressure in the passage way of an attenuator to provide a stabile air volume measurement.
